Problems and Solutions

• Wait for recording and other operations to end.
• If the problem persists, turn the camera off.
• If the camera does not turn off, remove and reinsert the battery.

• If you are using an AC adapter, disconnect and reconnect the AC adapter.

  • Any data currently being recorded will be lost.
  • Data that have already been recorded are not affected by removing or disconnecting the power source.

• Have you changed the monitor mode? Choose a different monitor mode using the M button.
• Have you limited the choice of monitor modes available using the [Limit monitor mode selection] item in the setup menu? Adjust settings as required.
• Dust, lint, or other foreign matter on the eye sensor may prevent it functioning normally. Clean the eye sensor with a blower.

• Rotate the diopter adjustment control to adjust viewfinder focus.
• If adjusting viewfinder focus does not correct the problem, set the focus mode to AF‑S and the AF-area mode to single-point AF. Next, select the center focus point, choose a high-contrast subject, and focus using autofocus. With the camera in focus, use the diopter adjustment control to bring the subject into clear focus in the viewfinder.

• Is a memory card inserted, and if so, does it have space available?
• If you selected mode S after selecting a shutter speed of “Bulb” or “Time” in mode M, choose a different shutter speed.
• Is [Release locked] selected for [Slot empty release lock] in the setup menu?

• Is the camera in manual focus mode? To enable autofocus, select AF‑S, AF‑C, or AF‑F for focus mode.

• The camera may be unable to focus if:

  • the subject contains lines parallel to the long edge of the frame,
  • the subject lacks contrast,
  • the subject in the focus point contains areas of sharply contrasting brightness,
  • the focus point includes night-time spot lighting or a neon sign or other light source that changes in brightness,
  • flicker or banding appears under fluorescent, mercury-vapor, sodium-vapor, or similar lighting,
  • a cross (star) filter or other special filter is used,
  • the subject appears smaller than the focus point, or
  • the subject is dominated by regular geometric patterns (e.g., blinds or a row of windows in a skyscraper).
• In focus mode AF‑C, the focus point may flash while the shutter-release button is pressed halfway or the AF-ON button is pressed, indicating that the camera is no longer able to focus. The focus operation can be resumed by releasing and then pressing the button again.

• A beep does not sound when the camera focuses with AF-C selected for focus mode.
• The shutter and beep do not sound if [ON] is selected for [Silent mode] in the setup menu.
• The beep does not sound if [Off] is selected for [Camera sounds] > [Beep] in the setup menu.
• The beep does not sound in video mode.

Using a flash restricts the range of shutter speeds available.

• Flash sync speed can be set to values of ¹⁄₂₀₀–¹⁄₆₀ s using Custom Setting e1 [Flash sync speed].

• When using flash units that support auto FP high-speed sync, choose [1/200 s (Auto FP)] for Custom Setting e1 [Flash sync speed] for shutter speeds as fast as ¹⁄₈₀₀₀ s.

  • When [Electronic front-curtain shutter] is selected for Custom Setting d6 [Shutter type], the fastest shutter speed available will be ¹⁄₂₀₀₀ s.
  • When [Electronic shutter] is selected for Custom Setting d6 [Shutter type], the fastest shutter speed available will be ¹⁄₆₀ s and auto FP high-speed sync will not be activated.

• The effects of changes to settings that affect exposure and color are not visible in the display when [Adjust for ease of viewing] is selected for Custom Setting d10 [View mode (photo Lv)]. If [Show effects of settings] > [Only when flash is not used] is selected for Custom Setting d10, display brightness will also be adjusted for ease of viewing (per [Adjust for ease of viewing]) when a flash unit is attached and ready to fire.
• Note that changes to [Monitor brightness] and [Viewfinder brightness] have no effect on pictures recorded with the camera.

• Are there smudges on the front or rear (mount-side) lens elements?
• Is there foreign matter on the image sensor? Perform image sensor cleaning.

• Shooting may end automatically to prevent the camera overheating, for example if:

  • the ambient temperature is high,
  • the camera has been used for extended periods to record videos, or
  • the camera has been used in continuous release modes for extended periods.
• If pictures cannot be taken because the camera is running hot, turn the camera off and wait for it to cool before trying to take pictures again. Note that the camera may feel warm to the touch, but this does not indicate a malfunction.

• To reduce noise, adjust settings such as ISO sensitivity, shutter speed, or Active D-Lighting.
• At high ISO sensitivities, noise may become more noticeable in long exposures or in pictures recorded when the camera temperature is elevated.
• Randomly-spaced bright pixels, fog, or bright spots may arise as a result of increases in the temperature of the camera’s internal circuits. Turn the camera off when it is not in use.
• Randomly-spaced bright pixels, fog, lines or unexpected colors may appear if you press the X button to zoom in on the view through the lens during shooting.
• Note that the distribution of noise in the display may differ from that in the final picture.
• This issue can sometimes be addressed by checking and optimizing the image sensor. Perform pixel mapping using [Pixel mapping] in the setup menu.

• White balance bracketing is not available when an NEF (RAW) or RAW + JPEG/HEIF option is selected for image quality.
• White balance bracketing cannot be used in multiple exposure and HDR overlay modes.

• Is [OFF] selected for Custom Setting a11 [Built-in AF-assist illuminator]?
• The illuminator does not light in video mode.
• The illuminator does not light when AF‑C or MF is selected for focus mode.

• Confirm that the appropriate option is selected for [Audio input selection] in the video recording menu.
• Is [Microphone off] selected for [Audio input sensitivity] in the video recording menu?
• Was the video recorded with [Audio input sensitivity] > [Manual] chosen in the video recording menu and a low sensitivity selected?

• Is [OFF] selected for [Auto-rotate pictures] in the playback menu?
• Auto picture rotation is not available during picture review.
• Camera orientation may not be correctly recorded in photos taken with the camera pointing up or down.

Pictures taken with [HLG] selected for [Tone mode] may not display correctly when viewed on other devices (for example, when output to other devices directly or when opened on a computer after upload). View the pictures on an HLG-compatible computer or other device. For more information on viewing HLG pictures on a computer, visit the following website:

• The pictures cannot be further edited with this camera.
• There is insufficient space on the memory card to record the retouched copy.

• Print JPEG or HEIF copies of the pictures created using a tool such as the [RAW processing (current picture)] or [RAW processing (multiple pictures)] items accessible via [Retouch] in the playback i menu.
• Copy the pictures to a computer and print them using NX Studio or other software that supports the NEF (RAW) format.

• Confirm that an HDMI cable is correctly connected.
• Photos taken with [HLG] selected for [Tone mode] may not display correctly on devices that are not HLG-compatible.
• Videos may not display correctly when viewed with [ON] selected for [External rec. cntrl (HDMI)] in the video recording menu.
• Pictures may display correctly if default settings are restored using the [Reset all settings] item in the setup menu.

Image sensor cleaning changes the position of dust on the image sensor and will not have the desired effect if:

• Image Dust Off reference data recorded after image sensor cleaning is performed are used with photographs taken before image sensor cleaning is performed, or
• Image Dust Off reference data recorded before image sensor cleaning is performed are used with photographs taken after image sensor cleaning is performed.
